Daredevil Dean Potter has been tightrope walking, climbing, and wingsuit flying for 27 years, but for the last handful – he hasn't balanced, jumped or flown alone.

That's because he's had Whisper, his 4-year-old Australian Cattle Dog, by his side. Or on his back.

Video of Potter and Whisper BASE jumping from over 13,000 feet off of Mount Eiger in Switzerland last summer has now gone viral.

While Potter says Whisper has loved experiences like this, some people are worried about the safety of the dog.

So we asked the adventurer to expand: What are five things people should know about him and his BASE jumping pet?

1) I'M A NATURALIST:

Potter says he's a naturalist and compares himself to John Muir. Since that famous wildlife expert traveled with his dog into the mountains in Alaska, Potter says "what I'm doing is nothing new really." He calls himself a 'very primitive guy' with a 'very strong connection to nature' where 'it just seems natural to bring my dog with me.'

2) THIS IS NOT WHISPER'S FIRST ADVENTURE:

While some humans may get out in nature occasionally, Whisper seems to hit the trails and the skies pretty regularly.

3. Kids invent a new game
It’s called “Throw Your Brother Down the Stairs in a Box.” And whoever is taping approves. (Don’t worry, the kid is okay!)

2. Bill Murray’s speech to a bachelor party
Murray wasn’t there with the party but he was certainly willing to lend his thoughts on whether you should really marry someone. I wonder if he gave the bachelor any second thoughts?

1. 50 Cent’s terrible opening pitch
Is he really that bad at pitching or did he just want to make some headlines? Either way, he won, because we were all talking about this.
